Pinocchio: You sure do!
The opposite of a Painful Transformation, one that the recipient and/or victim doesn't feel.
Usually done with the transformee transforming in their sleep to wake up to their new form, or the transformee gradually changing over time. Stock phrases include: "Why is everyone taller/smaller?" and "Why are you looking at me like I've got the head of an [animal]?" Such characters frequently end up Stumbling in the New Form for a bit before figuring out why they're stumbling. If they got bigger, they may assume their clothes Shrunk in the Wash.
Always a result of a Forced Transformation or Involuntary Shapeshifting, as a Voluntary Shapeshifter would know when they're transforming themself (unless suffering from Power Incontinence). They may discover their transformation in a Mirror Reveal or via Hands Looking Wrong.

Skid and Pump are so caught up in the story neither notice the shadows crawling up their bodies, to Candy Dealer's amusement. Skid and Pump do notice Skid has abruptly sprouted a tail, but both decide not to bring it up.
- Unleashing of a Dark Night: Sonic's first Werehog transformation was this, as it occurred while he slept. Without waking him up whatsoever, only discovering this after he has a dream involving this form.
- In Bartok the Magnificent Ludmilla barely notices her transformation into a dragon. It's an interesting variation considering that she knows she's turning into something, but not exactly what that is, assuming she's going to become more beautiful.
- Disney Animated Canon:
- Brother Bear: Kenai doesn't realize that he has been transformed into a bear until Tanana tells him that she can't speak Bear. This caused him to go check his reflection in the river and then he does a full-body check on himself, ending with him wagging his tail.
- The Emperor's New Groove: Emperor Kuzco is completely unaware that he's being turned into a llama at Yzma's dinner. When he meets Pacha, there's plenty of confusion until Pacha tells Kuzco to wiggle his fingers in front of his face. That's when he notices his hoof instead of his hand.
- Moana: After Moana saves Maui and recovers his hook (that lets him transform into animals), Maui starts to thank her, but is oblivious to the fact that his transformation malfunctioned and he's talking while having the upper half of a shark.

It's not until Tiana sees herself in the mirror that she realized she turned into a frog.
- My Little Pony: Equestria Girls:
- The transformations produced due to crossing the portal between the Pony and Human worlds are barely noticeable. In fact, in the first film Twilight doesn't even notice that she is a human until a dog-turned Spike tells her she has changed as well.
- Neither do humans Twilight and Rainbow Dash in the special Spring Breakdown, until Sunset uses her horn to illuminate the cave they are in, allowing them to see Sunset's Pony form and realize what happened. (It's also worth noting that the only reason Sunset knows they are in Equestria is because she realized the "quicksand" they found was just sand covering the portal they later used, and not due to the transformation.)
- The Super Mario Bros. Movie:
- After grabbing the Super Bell, it takes Mario a few moments of instinctively licking his paws to register his change into Cat Mario.

- In Casper: A Spirited Beginning, it isn't until Casper is thrown off a ghostly train, travels to the nearby city of living people and then unintentionally scares the hell out of everyone until he finally looks down at his feet and realizes that he doesn't have them anymore, leading him to discover that he indeed turned into a ghost.
- In Scooby-Doo: Monsters Unleashed, Scooby and Shaggy stumble upon a secret laboratory, and Scooby drinks some liquid in a fridge, which turns him into a tentacled blob.

- In The Witches Bruno Jenkins was unaware he’d been turned into a mouse until the boy who serves as the narrator points it out to him.
- The Worst Witch: In A Bad Spell for the Worst Witch, Mildred is at first startled by her tabby cat suddenly becoming much bigger; then she realises that everything else is much bigger, so she must be smaller. The truth only dawns when she discovers the Mundane Utility of being able to take a massive jump, sees her reflection in a mirror, and discovers that she has been turned into a frog.
- In Wizards of Waverly Place Justin dates a werewolf and learns to late that kissing one also makes you a werewolf. He's worried the transformation will be grueling but is informed it's quick and painless. In fact he's completed it without noticing in the moment this was explained to him as the camera cut away.
"I'm sure I'm fine."
- Later on Max doesn't realize he was accidentally turned into a little girl. First he got confused when someone called him a little girl, then looks around wondering about the changes in his body (i.e. his clothes are baggy, his fingers are tiny, his voice is high, etc.).
- We Are All Pokémon Trainers:
- When Callum turns into an Oshawott for the first time, he doesn’t notice until Sephy mentions hearing an Oshawott.
- Dio is completely unaware that he evolved into a Gliscor while asleep after grabbing the Razor Fang Kim dropped in his sleeping bag one night. When Dio wakes up, though, he is still perplexed of it until Sinatra points it out and tells Dio to look at himself, which he did, much to his initial shock. It wasn't until Dio sees his face in front of Kim's mirror that he realized he evolved, much to his sheer joy.
- In A Midsummer Night's Dream, Puck transforms Bottom's head into that of a donkey. Bottom doesn't even notice and scares off his costars in the play when he returns for his next lines. (Given the reason Puck transformed him required him to not be at all self-conscious, obliviousness could be a part of the spell; on the other hand, it wouldn't be noticeably out-of-character for Bottom to be just that dense, even when he starts braying and craving oats.)
- The beginning of Jak and Daxter: The Precursor Legacy shows Daxter being turned into an ottsel/Precursor after accidentally being knocked into a pool of Dark Eco. Apart from a sting, Daxter doesn't notice the change until he sees his hands, tail, and Jak staring at him in confusion.
- The Scagdead in Resident Evil: Revelations is a former crewman of the Queen Zenobia who underwent a Viral Transformation from the t-Abyss virus. Unlike many of the infected, he's still cognizant, but keeps telling the people attacking him (in self-defense) that he's still human, despite that being very obviously not the case.
- In Shantae and the Seven Sirens, using the Refresh Dance, which can rejuvenate certain undead and sickly enemies, near Rottytops will cause her to briefly change from a zombie to a human identical to her displaced soul from Shantae and the Pirate's Curse and how she appears in Shantae's memories in Shantae: Half-Genie Hero. She doesn't seem to notice and her idle animation remains unchanged.
- Buttersafe: Played for Laughs in "The Adventures of Gerald! The Guy Who Always Goes to Bed at an Overly Reasonable Hour." Gerald's parents tell him that they're both werewolves and have likely passed their lycanthropy to him, but since Gerald always goes to bed at an overly reasonable hour, he's inevitably asleep during the transformation and never realizes he's a werewolf, too ("I guess it skipped a generation?").
- As this is a transformation trope, it has appeared multiple times in El Goonish Shive:
- An old sketchbook comic shows Amanda not noticing that she is slowly shrinking.
- In the "Squirrel Prophet" storyline, Tedd went to the game store for a card tournament and until the middle of a match didn't realize that a) the enchantment that had turned his usually-purple hair pink had worn off, with him only figuring it out when someone else mentioned that they thought his hair was a different color and b) it had been replaced instead by one that turned him into a girl. Everyone else not noticing the latter was attributed to a combination of change blindness and Tedd looking pretty girly anyway.
- In the "Escape from the Mall" storyline, Catalina turns herself into a Cat Girl, and doesn't notice until she accidentally places her hand on her tail. Pandora, who is watching, explains why this happens.
- Whateley Universe:
- Mutant Gene Complex activation is like this, with the resultant iris change usually being sudden and unnoticed until someone points it out.
- In Absinthe, Adam has his hair obliviously change color. His mom notices first, then he notices when he looks in the mirror:
"Adam," Mom exclaimed, jumping and rushing to me. "What's wrong?" Then she blurted out, "Your hair..."
Just as I was about to climb into the shower, my muscles seemed to turn into rubber and I staggered, barely catching myself before I fell onto the floor. I grabbed the bathroom counter and used it to hold myself up, but then I noticed my reflection in the mirror.
"My hair," I gasped, staring at myself in blank confusion. My hair was... green.
- In the Batman: The Animated Series episode "Feat of Clay: Part 2", the shapeshifter villain Clayface first discovers his new powers when he involuntarily shapeshifts while looking at a series of pictures, becoming each one in turn. He is completely unaware of this, and probably wouldn't have even noticed it happening if someone else in the room hadn't pointed it out.
- One episode of Donkey Kong Country involves a device that can switch brains between characters, resulting in a number of characters switching bodies and not realizing it at first. Even after other characters point it out.
- In The Flintstones episode "Monster Fred", Fred and Dino inadvertently end up the guinea pigs for a mad scientist's device (that in theory is a personality-swapper but instead has a "Freaky Friday" Flip effect on the subjects). Somehow, after the fact, Fred is unable to notice that he is now a dinosaur even when Barney, Wilma, and Betty point it out to him (nor does Dino notice that he's now Fred). The same thing applies when further swaps occur at the climax (including Fred switching with Barney, the men switching with their respective wives, and Dino switching with the mad scientist's assistant).
- Exaggerated in the Gargoyles episode "The Mirror":
- Puck turns Elisa Maza, and soon all other humans in Manhattan, into gargoyles; and later turns the (actual) Gargoyles into humans (except for Bronx, whom he turns into a dog). All of these transformations come with a side of Fake Memories; the victims think that they've always been gargoyles/humans, and only begin to doubt it when the logical fallacies are noted. For example, Gargoyle Elisa knows that she's never flown, despite having wings; while the humanized Gargoyles know that they've flown, but can't explain how they did it.
- At the end of that same episode, Puck grants Demona's wish to no longer turn to stone during daytime... by making her turn into a human each day instead. She doesn't notice until she sees herself in the titular mirror, which she promptly breaks out of surprised horror. Every subsequent transformation is painful; Word of God says Puck specifically protected her from it this time so as not to spoil the surprise.
- Looney Tunes:
- In the short Duck Amuck, the animator draws Daffy an entirely new body, but Daffy doesn't notice until the animator draws him a mirror.
- Hyde and Hare ends with Bugs drinking the Hyde formula and becoming a green rabbit monster, and he questions why the people in the park are running away from him.
- In the Halloween Episode A-Haunting We Will Go, Speedy Gonzales standing in for Witch Hazel transforms Daffy into the same creature as Duck Amuck. Again, he doesn't notice, and in this case, still hasn't noticed by the end of the cartoon.
- Samurai Jack:
- In "Chicken Jack", an Evil Sorcerer curses Jack to turn into a chicken. Even though Jack is now much smaller and everyone else notices that he's a chicken, he doesn't realize what he's become until he does a Double Take of his image on a reflective surface.
- In "Episode XCIX", Jack buys and eats a strange snack from a street vendor. His head (very briefly) transforms and looks like a colorful fish; his friend Ashi stares at his face with confusion, but Jack has no idea why. By the time it wears off, Jack still hadn't noticed anything.
- The Scooby-Doo Show: In the episode "High Rise Hair Raiser", Scooby and Shaggy find a spellbook. Shaggy, not believing in magic, reads a random spell from it for laughs. The spell transforms him and Scooby into monsters, but they somehow fail to notice it, and have a laugh over the obviously "fake" spell. Shaggy then reads a counter-spell which turns them back to normal.
- In the Steven Universe episode "So Many Birthdays", Steven doesn't notice his Rapid Aging until Lars and Sadie fail to recognize him. Not even changing his own clothes helps him notice.
- In Episode 8 of Total Drama: Revenge of the Island, Dakota doesn't notice she's turning into a mutant until Chris gives her a mirror. Even then, she doesn't realize what is happening until Scott points out it is a mirror, rather then a picture like she thought.
- Xiaolin Showdown: Jack somehow inflicts this trope on himself multiple times with the Monkey Staff, a Wu that grants the wielder the powers and tail of a monkey, while slowly turning them into one. The first time, Jack only notices the tail and fails to realize the rest of the changes even as Wuya repeatedly points them out. The second time, Chase exploits Jack's obliviousness to the transformation in order to keep him out of Chase's plans. The real kicker is that the entire transformation can be instantly undone if the wielder simply lets go of the staff.
- Young Justice (2010): Miss Martian unconsciously changes her skin from green to Caucasian and has this pointed out by Black Canary. She freaks out at first because Canary said her skin was "white", and she is actually a White Martian, a subrace that's discriminated against on her homeworld, and she's been hiding this on Earth.
